As part of the scope of the job, Ringo performed the following tests to the MOV and Pneumatic valves:

Base line tests using a VIPER Diagnostic System to get the torque and thrust values by means of the strain gauges. In the case of the MOV Valves, diagnosis to get the motor power was performed at the same time using a SIPLUG diagnostic system in order to establish a relation between the actuator power and the valve torque and thrust values.

Valves were already shipped to the plant.
